I am switching over to an R/O DI unit because my tap water is so high in Silicates and Phosphate. Any suggestions on what I should use to treat the R/O water with before adding to the tank? I am thinking of just R/O right by Kent marine. The pH regulator made my Phosphate go off the chart. I have 2- monos and one Teminsis and 1- Jardini. Thanks you!
